  - Apex: fix groovy build result update

    The groovy script is working, but it is changing the 'apex test suite'
    phase to unstable and we really want it to change the 'scenario' job
    result to unstable if deploy passed but tests failed.  Therefore this
    patch moves the groovy plugin to execute on the scenario job, and looks
    for deploy successful before changing the build result.
